Benefits of technology

"The present invention provides a stroller with a folding device that allows for easy and convenient folding and extension. The stroller can be efficiently folded to minimize its size for packing, storage, and transportation. The stroller also has a simplified structure that reduces costs of fabrication. The folding device includes a main body, a socket, a slide plate, and a locking plate, which are all fixed on the support frame of the stroller. The slide plate is movably mounted in the receiving chamber of the socket and has a first section secured on the pull cord and a second section slidably mounted in the slideway of the socket. The locking plate is secured on the support frame and has a protruding locking hook that detachably locks in the locking slot of the second section of the slide plate. This design ensures that each folding device is fixed on the support frame by the slide plate and the locking plate."
